4.5.1 Cache I/O Performance

Cache I/O performance is displayed on the Cache I/O performance panel of the CSG Web GUI dashboard.
You can check the cache I/O performance to determine if the cache performance is creating a bottleneck when transferring to the cloud provider.

Figure 4.7 Example of Information Displayed on the Cache I/O Performance Panel

Cache I/O performance is displayed as a line graph in five minutes increments. The display range covers two days (fixed).
The light blue line graph indicates Cache I/O performance(Read), and the dark blue line graph indicates Cache I/O performance(Write).

If you focus any area on the graph, the date, time, and performance information is displayed for that tooltip on the graph.
